In Er3+/Yb3+codoped Na2O-ZnO-PbO-GeO2-TeO2(NZPGT) glasses, effective ~1.5mm infrared (IR) emission was investigated under 980nm excitation. Judd-Ofelt intensity parameters Wt (t = 2, 4, 6) had been calculated to be 6.78´10-20, 1.54´10-20, and 1.17´10-20cm2,respectively. The IR emission full width at half maximum (FWHM) is 73nm, and the maximum stimulated emission cross-section (se) is derived to be 7.53×10-21cm2. A figure of merit (FOM) as the product FWHM´se is adopted to evaluate the gain bandwidth. The comparison of FOM in different glasses indicated that Er3+/Yb3+codoped NZPGT glasses were potential materials in developing broadband optical amplifier.

The incorporation of cascaded and hybrid-type optical amplifiers into the optical fiber link is advantageous for the purpose of achieving wide gain bandwidth of multi-wavelength coarse wavelength division multiplexing (CWDM) systems. Different amplifiers whose operating gain region differ from each other are connected in cascade, thus providing better gain performance as the overall gain is combined and flattened over a larger spectrum. In this paper, the effect of the crossover of the uniform gain of the semiconductor optical amplifier (SOA) and the nonuniform gain of erbium-doped fiber amplifier (EDFA) is analyzed using an in-line cascaded SOA-SOA and an in-line hybrid SOA-EDFA configuration in the amplification of an 8-channels CWDM system obtained from the simulation using Optisystem software. It was observed that the cascaded SOA-SOA produces higher gain of 25 dB and wider gain bandwidth of 60 nm compared to the hybrid SOA-EDFA configuration with maximum gain of only 24 dB and 40 nm bandwidth. In addition, better bit-error-rate (BER) performance which is within the typical values in optical fiber communication is also achieved from the cascaded SOA topology. Wider gain bandwidth obtained with the SOA-SOA configuration would permit the transmission of video application at 1551 nm in the proposed Ethernet CWDM system transmitted at 100 Mb/s data rates.

AbstractAmplification through hybrid optical amplifiers (HOAs) is a propitious and proficient technology for high speed and high capacity dense wavelength-division-multiplexing (DWDM) systems. HOAs are intended to improve system reach and to accomplish wide gain bandwidth with enhanced flatness of gain. In this work, an ultradense 16 channel WDM system is demonstrated and performance of diverse hybrid amplifiers is evaluated in terms of output power, Q-factor, gain flatness and BER. Spacing among the WDM channels is 25 GHz in order to make system bandwidth efficient and scrutinized its effect on four wave mixing (FWM) in case of EDFA-EDFA, Raman-EDFA and SOA-EDFA. It is observed that SOA-EDFA is more and Raman-EDFA is less prone to FWM. Moreover, for distance 20 Km–140 Km, Raman-EDFA is optimal configuration for amplification and from 150 Km–200  Km, SOA-EDFA shows better performance. For prolonged link lengths such as beyond 200  Km, EDFA-EDFA is a right hybrid amplifier. In order to achieve maximum gain flatness in proposed architecture, EDFA-EDFA is recommended to use.

<p><em>Abstrak </em><strong> - Antena merupakan alat pemancar yang akrab dengan aktifitas sehari-hari dan mudah sekali dijumpai, di rumah, di gedung, bahkan pada alat komunikasi yang digunakan. Salah satu antena yang sering digunakan adalah antena televisi. Antena televisi yang sering digunakan adalah Yagi-Uda yang biasanya dipakai sebagai outdoor antena dan antena dipole yang biasanya digunakan untuk indoor antena. Masing – masing jenis antena memiliki kriteria dan keuntungan berdasarkan dari kebutuhan penggunaannya. Baik antena dipole maupun antena Yagi-Uda memiliki perbedaan diantaranya adalah besar bandwidth, nilai gain, dan pola radiasi. Pada paper ini dapat diketahui bahwa bandwidth yang dimiliki antena yagi-uda lebih besar daripada antena dipole yakni 0.39943 MHz untuk antena yagi-uda dan 0.16569 MHz untuk antena dipole. Begitupula dengan besar Gain yang dimiliki antena Yagi-Uda (6.64 dBi) lebih besar dibandingkan dengan gain dari antena dipole (2.29 dBi). Perbedaan ini dikarenakan faktor elemen director dan ketebalannya.</strong></p><p><strong><br /></strong></p><p><strong><em>Kata Kunci</em></strong> – <em>Atena Televisi, Atena Yagi-Uda, Atena Dipole, Gain, Bandwidth</em></p><p><em> </em></p><p><em>Abstract</em> <strong>- Antenna is a transmitter tool that is familiar with daily activity and easy to find at home, in the building, even on the communication tool used.
